"Even if a devotee commits the most abominable actions, he is to be considered saintly because he is properly situated'' [BG 9.30]. As you will say, "To err is human'', so in the neophyte stage we may always expect some discrepancies are there. Kindly see the things in this light and forgive their small mistakes. The big thing is they have given their life, everything to Krishna - that is never a mistake.
